Answer:
Explanation:
A pencil in the picture shows a segment with a definite length.
We may get confused with the difference in a line and segment.
A line is defined by a line of points that extends infinitely.
That means both the ends of a line are not defined.
But a segment is a part of line which has a definite length between two defined ends.
Therefore, unsharpened pencil defines the term line segment which is a defined term.
